Why didn't Attic-us Finch believe firmly in the integrity of their courts and in the jury system?

Atticus Finch, in Harper Lee's "To Kill a Mockingbird," struggles with the integrity of the courts and the jury system due to the pervasive racism and social injustice in Maycomb. He understands that, despite the legal framework that should ensure fairness, deep-seated prejudices often skew the outcomes of trials, particularly for marginalized individuals. Atticus's experiences, particularly in defending Tom Robinson, highlight the limitations of a system that can be swayed by societal biases rather than truth and justice. This skepticism reflects his awareness of the moral complexities inherent in human nature and the legal system.
